DETAILED DESCRIPTION

While techniques exist for testing a current device's capabilities as they relate to system requirements of a collaboration, there exists a need for determining the capabilities of other known user devices as they relate to a collaboration and providing a ranking accordingly. The method and system disclosed herein enable analyzing a set of known user devices according to their compatibilities with a collaboration. The present invention will now be discussed with respect to the Figures.

FIG. 1 depicts a block diagram of components of a device ranking system 100 in accordance with at least one embodiment of the present invention. As depicted, device ranking system 100 includes two participants 110, a calendar management system 120, a conference management system 130, a security context system 140, rank information storage 150, and registered device storage 160. Device ranking system 100 enables analysis and ranking of one or more user devices with respect to a collaboration of interest.

As depicted, each of the two participants 110 has a plurality of registered devices 112. In the depicted embodiment, each participant 110 has 3 registered devices 112, but it should be understood that in other embodiments there may be any number of participants, and each participant may have any number of registered devices. In some embodiments, each registered device 112 corresponds to a device that the participant 110 has registered with the security context system 140. Each registered device 112 may be a desktop computer, laptop computer, specialized computer server, tablet, cellphone, or any other electronic device or combination of electronic devices capable of accessing a collaboration of interest.

Calendar management system 120 may be an online calendar managed or accessed by any participant 110. In some embodiments, calendar management system 120 corresponds to a system that hosts a web application that allows one or more users to edit, and optionally share with other users, online access to a calendar. In some embodiments, calendar management system 120 provides one or more scheduled events to a conference management system. Calendar management system 120 may additionally provide event details for the one or more scheduled events, such as listed participants, scheduling information, location information, or event details. In some embodiments, calendar management system 120 provides one or more scheduled events responsive to receiving a query from either conference management system 130 or device analysis system 140.

Conference management system 130 may be a system or server capable of hosting various collaborative services. Collaborative services may include applications for hosting webinars, webcasts, peer-level web meetings, or any other web-based collaboration applications. In some embodiments, conference management system 130 enables real-time point-to-point communications as well as multicast communications from one sender to many receivers.

With respect to the depicted embodiment, registered device storage is configured to store received information corresponding to the one or more registered devices 112. While in the depicted embodiment registered device storage 160 and rank information storage 150 are implemented separately, it should be appreciated that rank information and registered device information may be stored together in other embodiments.

FIG. 2 is a flowchart depicting a device analysis method 200 in accordance with at least one embodiment of the present invention. As depicted, device analysis method 200 includes receiving (210) meeting information and device information, determining (220) contextual information corresponding to the meeting, calculating (230) compatibility metrics for one or more participant devices, ranking (240) according to the calculated compatibility metrics, determining (250) whether a context change has occurred, providing (260) the device rankings, and enabling (270) access to the collaboration according to the device rankings. Device analysis method 200 may enable a user to determine which of his/her devices is the most adequate for accessing a collaboration.

Receiving (210) meeting information and device information may include receiving a list of participants for a collaboration of interest, as well as scheduling information for said collaboration. In some embodiments, receiving (210) meeting information includes receiving device information corresponding to one or more registered devices for each of the participants. Device information may include device type (computer, tablet, phone, etc.), security credentials, device features (webcam, microphone, etc.), networking capabilities, device owner, or any other characteristic of a device capable of connecting to a collaboration service. In some embodiments, receiving (210) meeting information includes enabling users to register one or more devices.

Determining (220) contextual information corresponding to the collaboration may include identifying one or more device features or capabilities required to effectively participate in the collaboration of interest. In some embodiments, determining (220) contextual information corresponding to the collaboration includes determining minimum system requirements for accessing the collaboration of interest. Additionally, the determined contextual information may include features that are not required but can be used to rank devices further. For example, a collaboration may not indicate a certain image quality corresponding to a device's camera, but a device's camera's image resolution can be used to rank devices. Some contextual information may simply be pass or fail conditions; in other words, the contextual information may indicate features that a device must have to participate in the collaboration. Other features included in the contextual information, as discussed above, may not be required, but can be analyzed to contribute to a device ranking.

Calculating (230) compatibility metrics for one or more participant devices may include determining the compatibility of each registered device with the determined contextual information. In other words, calculating (230) compatibility metrics for a participant device includes analyzing said device with respect to each of the features indicated by the contextual information. For example, if the contextual information indicates that the collaboration of interest is a video conference, the contextual information may indicate a minimum connectivity rating, a camera, and a microphone are required to take part in the collaboration. Additionally, the contextual information may indicate that devices with higher connectivity ratings and higher camera resolutions are ranked higher. With respect to this contextual information, calculating (230) compatibility metrics includes determining whether a participant device meets each of the pass fail conditions. In this example, if a device lacks a camera or microphone, or does not meet the minimum connectivity rating, then the device is flagged as incompatible with the collaboration. Each device that passes each of these conditions is then analyzed according to its camera resolution and connectivity rating. weighted more heavily than others when calculating the total device ranking.

Ranking (240) according to the calculated compatibility metrics may include determining a ranking for the one or more registered devices according to the calculated compatibility metrics. With respect to the example discussed previously, a device with a higher camera resolution will be given a superior ranking, and a device with a higher connectivity rating will be given a higher ranking. In some embodiments, the rankings with respect to the individual features are averaged to provide a total device ranking. Certain features may be weighted more heavily than others. For example, a device's connectivity may be weighted twice as heavily as a devices camera resolution.

Determining (250) whether a context change has occurred may include monitoring whether the collaboration details have changed. Examples of a context change include a change in event type, a change in participants, a change in time, or a change in the associated device requirements. In some embodiments, a collaboration service may be configured to provide an alert any time the collaboration details are updated. If a context change has occurred (250, yes branch), the method continues by returning to calculating (230) compatibility metrics. If a context change has not occurred (250, no branch), the method continues by providing (260) the device rankings.

Providing (260) the device rankings may include providing the determined device rankings to the users of said devices. In one embodiment, providing (260) the device rankings includes displaying only the rankings of devices registered by a particular user to said user. Providing (260) the device rankings may additionally include providing the determined rankings to a storage location. In some embodiments, the device rankings may be stored in the same place as the initial device registration information.

Enabling (270) access to the collaboration according to the device rankings may include granting collaboration access to one or more registered devices according to the determined device rankings. For example, if device rankings are calculated according to some security attribute or feature of the devices, it may be detrimental for a device that falls below the minimum security requirements to have access to the collaboration. Therefore, such a device may be denied access accordingly. In other embodiments, each user may be allowed to access the collaboration via only a single device at a time. In such embodiments, a user may be able to either select any of his/her devices that meet the minimum device requirements, or may be required to use his/her highest ranked device to access the collaboration to facilitate the best collaboration results for all participants.
